( Jones et al, 2014 ) A cell can be divided into two types of cell, animal cell and plant cell. A plant cell is usually bigger than animal cell. Both cells have similarities such as having nucleus, plasma membrane and cytoplasm. These are all the common features present in both the animal and plant cell. However, a unique structure that plant cells have is cell wall, large central vacuole and chloroplasts which are absent in animal cells.
Plant and Animal cells Introduction: Cells can be all shapes and sizes; they form the basic structure of the plant or animal. Cells also help living things stay alive, and each organelle in the cell has its own function. There are two main types of cells: Eukaryotic cells (cells with a nucleus), and Prokaryotic cells (cells without a nucleus). The aim of this report is to explain cell theory, to compare and contrast animal and plant cells. I will also include comparisons of the organelles to a factory to help better understand the works of a cell.
Chlorophyll looks green because it absorbs red and blue light, making these colors unavailable to be seen by our eyes. It is the green light which is not absorbed that finally reaches our eyes, making chlorophyll green. However, it is the energy from the red and blue light that are absorbed that is, thereby, able to be used to do photosynthesis. The green light we can see can’t be absorbed by the plant, and thus cannot be used to do photosynthesis. The chemical reaction involved in photosynthesis is 6CO2 + 6H2O + sunlight -> C6H12O6 + 6*O2.
Fungi Unlike bacteria and viruses, fungi are simple plant-like organisms which reproduce using spores. There are three types of fungal infections; ones which occur on the surface of the skin and hair; those which occur in the epidermis (such as ringworm and athlete's foot) and those which affect the deeper layers of skin – the dermis, subcutaneous tissue, muscle and fascia. Fungi may reach these layers as a result of penetrating wounds, or may be inhaled. Parasites Parasites differ from bacteria in that they need a living host to survive and reproduce, although not all parasites affect the host. Parasites can be acquired through contact with a contaminated surface, via infected water or food and through contact with contaminated bodily fluids such as blood, faecal matter and sexual contact.
The cells in a tissue may not be identical to each other, but the origin is the same for each one. The four type of tissues are found in multicellular animals, and very depending on species. Every function of the body is executed through cells and the importance of each cell of a particular animal or plant could never be underestimated. 8. Identify the four fundamental types of tissues and give their functions.
CONTROLLED VARIABLE: The type of salt, type of distilled water, potato size, beakers/test tubes size, type of potato, location/storage, time, and amount of solution. BACKGROUND RESEARCH: The cell membrane (plasma membrane) surrounds all living cells, and it’s the most important organelle of the cell. It controls how substances to move in and out of the cell and it’s responsible for many other properties of the cell. The membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The cell membrane is semi-permeable because it allows some substances to pass through and some substances cannot pass.
Photosynthesis Compared to Semiconductor-Based Solar Cell Energy Natural Energy vs. Electrical Energy Abstract Energy is the ability to do work. Energy is in everything. Without energy the world as we know it would simply not exist. Energy can came from many things - be it thermal energy, kinetic energy or electrical and chemical energy. Plants use a process called photosynthesis to obtain their energy and people sometimes use solar energy.
Introduction All cells have plasma membranes which are selectively permeable meaning only some materials are able to move across it either to enter or exit the cell. The ability of a molecule to cross the plasma membrane depends on its size, hydrophobicity and charge as well as the relative concentration inside and outside of that cell (Biology Department, 2010). When molecules move from high concentration to low concentration it is called diffusion. More specifically when water diffuses across a cell membrane it is called osmosis. If the concentration of water in a cell is lower than the concentration of water in the solute the solution is said to be hypotonic and the cells swell because they will take up water.
Photosynthesis takes place primarily in plant leaves, and little to none occurs in the stems. The parts of a typical leaf include the upper and lower epidermis, the mesophyll, the vascular bundle(s) (veins), and the stomates. The upper and lower epidermal cells do not have chloroplasts, thus photosynthesis does not occur there. They serve primarily as protection for the rest of the leaf. The stomates are holes which occur primarily in the lower epidermis and are for air exchange: they let CO2 in and O2 out.
The two cells we observed were eukaryotic cells, one was an animal cell and the other was a plant cell. In the animal cell we saw the nucleus, cytoplasm, and the cell membrane. It was an irregular shape but more round than anything, the size was on the small side. While observing the plant cell we saw the cell wall, nucleolus, cytoplasm, and the nucleus. We could not see its cell membrane.
